How to Use

In this step, you authenticate your account with Twitter Archive Eraser so that it can delete the tweets you select. This works by providing a PIN number that twitter provides after the authentication.

Note: from version 4.0 on, you need to accept sharing several statistics to use Twitter Archive Eraser.

Delete Tweets: Download your twitter archive (from https://twitter.com/settings/account) then load it directly as a zip file into Twitter Archive Eraser (new in version 4.0).
Select the tweets to delete grouped by months time range. There is no limits on the number of tweets you can load / delete.

Once you have selected the months of tweets (or retreived the favorites / DMs) you wish to delete, you are now presented with all the tweets in this period of time.

By default, all the tweets are marked for deletion. If you want to keep any specific tweets, just uncheck them as shown in the pictures.

To search for tweets, use the filter field. Check the 'Regular Expression Matching' option to search using RegEx patterns.

In case of Favorites / DMs, check the 'Filter Based On Username' To search for keywords matching the username rather than the tweet contents.

You can also choose the degree of parallelism you want: that is how many tweets Twitter Archive Eraser deletes at a time: the more the better. Notice however that this parameter is limited by your network speed.

You can pause/resume the deletion process and check/uncheck tweets in between.

There is no Step 4!
